Regular expressions newbie: something for templates

Skip's example would be faster than mine because I used .*? which has 
problems when the amount of content matched is large.

Another way to spell this:
re.sub("\$([^$]+)\$","%(\g<1>)s",s)
or:
re.sub("\$(?P<body>[^$]+)\$","%(\g<body>)s",s)

Also Skip used a raw string r"xxx" which I should have done as well.
The doc explains the problem with not using raw strings. 
Has to do with back slash hell.

Now if I can make all this nice stuff a habit :)
